Fluorimetric measurement of adrenocortical steroids in concentrated acid solution

Chromogenic and fluorogenic reactions of adrenocortical and other steroids in concentrated acids.

Excretion of individual adrenocortical steroids in obese children.

Savage, D. C. L., Forsyth, C. C., and Cameron, J. (1974). Archives of Disease in Childhood, 49, 946. Excretion ofindividual adrenocortical steroids in obese children. The excretion of 13 individual adrenocortical metabolites in the urine of 21 obese children aged 7 months to 16 years is reported. Fractionation of the steroids was carried out on 24-hour samples of urine by paper chromatography u...

Measurement of pH in concentrated brines

Accurate measurement of pH in concentrated brines is a critical aspect of materials testing in the oil and gas industry. Concentrated sodium chloride solutions, typically up to 4 M and saturated with carbon dioxide, are often used to simulate production water during testing programmes. The pH of the solution may be adjusted to the desired value by the addition of sodium bicarbonate (to raise pH...

The Determination of Adrenocortical Steroids and their Metabolites

This short symposium attempts to collate the methodology current in 1953 for studies of the adrenocortical steroids. As has become the custom at meetings of this nature, little original material is presented. A notable exception to this is the preliminary report by Simpson and Tait of their isolation of electro-cortin, or aldosterone as it is now called, from adrenocortical extracts and of the ...
